Surface water controls at Covel Gardens are designed to maintain natural drainage patterns, prevent rainfall from coming in contact with leachate or refuse and minimize erosion. The Covel Gardens design allows for three stormwater outfall points. Currently, only one of the outfalls is in use. All surface water is controlled through a series of drainage ditches that direct the water to a sedimentation pond.
The sedimentation pond holds the water so that it can be discharged in a controlled manner. This method allows soil particles to settle to the bottom of the pond rather than be discharged off site. Storm water discharge samples are collected and analyzed on a semi-annual basis from the designated outfall.
